1. A method for service processing in optical transport network, comprising:
mapping a client service into a service container; and
mapping the service container into an optical transport network frame,
wherein a payload area of the optical transport network frame consists of payload blocks, each of the payload block comprises an overhead area, and the overhead area comprises an indicator being used for indicating whether data carried by the payload block is service container data or stuff data,
wherein in the payload area of the optical transport network frame, multiple consecutive payload blocks are used as a transmission period, and
mapping the service container into the optical transport network frame comprises:
calculating the number N1 of payload blocks that need to be occupied by the service container in one transmission period according to a bandwidth of the service container and a bandwidth of the payload blocks;
determining distribution locations in the transmission period of payload blocks that need to be occupied by the service container based on a preset allocation algorithm according to the number N1 of payload blocks that need to be occupied by the service container in the transmission period; and
mapping the service container into the payload blocks at the determined distribution locations,
wherein in one transmission period, for the payload blocks for bearing the service container, in a case that data size of the service container data buffered in a service container cache area exceeds a size of one payload block, the service container data is carried in the payload block; otherwise, the stuff data is carried in the payload block.
